The ratio of the constant of proportionality is (1, 30).
To find the ratio of the constant of proportionality, we need to compare the number of pages read to the time spent reading.
From the table, we can see that when Ruth reads for 1 hour, she reads 30 pages.
Therefore, the ratio of the constant of proportionality is (1, 30).
To find the ratio of the constant of proportionality, we need to find the relationship between the number of pages read and the time it takes. From the table, we can see that as time doubles, the number of pages read also doubles.
Notice that from the first data point to the second data point, the time doubles from 1 hour to 2 hours, and the pages read also doubles from 15 pages to 30 pages.
Therefore, the ratio of the constant of proportionality is (2, 60).
